Patented July 12, 1932 UNITED STATES PATENT OFFICE I WALTER E.HUENEFELD, OF CINCINNATI, OHIO, ASSIG-NOR TO THE HNENEFELD COM- PANY, OFCINCINNATI, OHIO, A CORPORATION OF OHIO CONTAINER Application filedJanuary 24, 1929. serau No. 334,793.

My invention relates to containers, and particularly to a novel type ofcontainer having a self-locking closure.

It is the object of my invention to provide .5 a container with a lidwhich will carry looking device, which, when the lid is applied to thecontainer, will interlock with an inturned bead formed at the top edgeof the container. It is further my object to provide screw headed boltsfor the locking de vices which will enable the receiver of the containerto release the locking devices so that the lid may be removed.

As in all such packages for goods, it is an essential qualification thatthe container be inexpensive to make and also that it shall be of strongand rugged construction so that it will withstand shipping. It is myobject to provide a container which will respond to such qualifications.

The above and other objects to which reference will be made in theensuing disclosure I accomplish by that certain combination andarrangement of parts of which I have shown a preferred modification.

Referring to the drawings Figure l is a perspective view of the lid.

Figure 2 is a bottom perspective view of a portion of the lid showingthe preferred type of locking device.

Figure 3 is a sectional view through a container showing the containerwith the lid locked in position thereon.

Figure 4 is a perspective View of a modi- 7 fied type of locking device.

The preferred type of container is circular in shape and is preferablymade from metal,

although it may take other shapes, and the material is not a limitation.The container has a side peripheral wall 1 and a bottom 2, the sidesbeing provided, if desired, with suitable reinforcing corrugations suchas are indicated at 3. The top edge of the peripheral wall is formedwith an inturned bead 4 which will ordinarily have an annular slotdevices.

5 within which the locking devices seat. I

This bead serves for a shoulder and a shoulder can be formed in variousways. In wood a groove might be cut, or in paper a band might beexpanded or riveted near the top. Also, the shoulders can be spaced.

The lid for the container shown is preferably of the friction type,having a downturned wall 6 which frictionally engages the outer surfaceof the container wall. At radially spaced positions in the lid there aredepressed portions 7 which seat the lockin The locking devices arecomposed of metal clips having a straight shank 8 through whichscrew-threaded bolts 9 may be passed. The bolt may either be securedwith a nut 10, as indicated in Figures 2 and 3, or the hole through theshank piece may itself be'threaded, as indicated at 11 in Fig ure 4. IThe locking devices have return bent outer ends 12 which, when the lidis applied to the can, lock under the bead formed at the top edge of thecontainer wall.

The locking devices are so spaced from the edge of the lid that when thelid is applied the return bent portion is resiliently contracted at thereturn bend of the device so that as the lid seats on the container theends of the clips will snap into place thereby snugly locking the lid inplace.

In removing the lid the receiver uses a screw-driver to'unscrew thebolts, and as soon as the bolts are turned clear off, the spring clipswill remain within the can and the bolts maybe removed with the lid.

If fiber. containers or wooden tubs are used, the top edge of the wallswill have to be pro- .vided with inturned beads or lugs to provide theshoulders with which the spring clips will interlock. In wooden tubs,for example,

annular ledges might be cut in the wall of the tub on the inner sidejust below the top, so that the spring clips maylock under the annularledge.

I When the idea is once understood, modifiin said lid with threadedbolts, said bolts having slotted heads disposed exteriorly of said lid,and nuts for attachment interiorly of said lid.

6. A container having an inturned annular bead at the upper edge thereofand a lid having radially-spaced locking devices for engaging saidinturned bead, said locking de-' vices being demountably secured in saidlid, and being releasable exteriorly of said lid, said locking deviceshaving flat shanks, and return bent extensions of said shanks adapted toresiliently lock place under said inturned bead.
